TECHSEAL RDL 940/941RDL 940 (GUN GRADE) / RDL 941 (POUR GRADE)TECHSEAL POLYSULPHIDE SEALANTDESCRIPTIONTECHSEAL RDL 940/941 are two component sealant based on THIOKOL Polysulphide liquid elastomer. It consists of a base compound and accelerator (Curing Agent). When the two components are mixed together prior to application, a chemical reaction is initiated which cures instantly to a firm, flexible rubber like seal with excellent adhesion to concrete, masonry, wood, glass, acrylic and PVC plastics. It is capable of withstanding repeated extension, compression & cyclic movements without the loss of adhesion and resists deterioration by weathering, sunlight, ozone, water, salt, oils and fuels. It is far superior to all the conventional joint sealing material like bitumen, mastics, metallic channels and expansion sheets.RDL-940 (Gun Grade) is a non-sag material used for sealing of horizontal, vertical & ceiling jointsRDL-941 (Pour Grade) is a pourable & self leveling material used for sealing of horizontal joints onlyFEATURES / ADVANTAGES Cures at ambient temperatures to a tough, elastic and flexible rubber like material Bonds strongly to most of the building materials with the use of recommended primers Durable, remains unaffected by UV rays, ozone and weathering conditions Resistant to water, salt water, 10% dil. acids except nitric acids, alkalis, most of the common chemicals, vegetable, lubricating oils and fuels Performs well in a temperature ranging from 20C to 80C Slip resistant (sag) can be applied in horizontal joints Movement capability Provides satisfactory hermetic sealing of the joint subjected to expansion, contraction, vibration and cyclic movement within the following limits. -Movement joints up to 25% of the width Slip resistant (non-sag) can be applied in vertical & ceiling g joints Self leveling, after pouring in horizontal joint levels itself Resilient. Recovers the original width after expansion & contraction without loosing the surface bond Excellent reparability property It can be over coated by waterproofing compounds Non-toxic Sealant will not cause staining to concrete masonry or stonesTYPICAL APPLICATION Sealing of expansion, contraction & construction joints in building structures such as, basements, subways, retaining walls, floors, external walls and claddings of high-rise buildings, roof terraces & ceilings especially structural expansion joints running through the ceiling
